GAS RANGE.

-. 'Application meavaugust 11, 1924.' vserial No. 731,318.

To all whom t may concern: y

Be it known that I, FREDERICK W. ROGERS, a citizen of the United States, residing at Beaver Dam, in the county of Dodge and State-'of Wisconsin have invented certain new and useful lmprovements in Gas Ranges, of which the following is a speci-A Hcatlon. z v

This invention relates to improvements inl ranges, 'and more particularly'to ovens therefor. v

Aniobject ofthe invention is Ato provide.

an oven which may be heated to and maintained at a desired temperature with the- Qonsumption of a minimum quantity. of

fuel.

I A further object'relates to thearrange-- ment of Hues whereby fresh air only is conducted into the oven; said airbeing preheated to a relatively high temperature before entering the oven, thus effecting a considerable saving of fuel.

l A further object` is to provide an oven in which the 'products of combustion from the combustion chamber are conducted around the oven proper to heatv the same without being admitted therein.

Further objects relate to various features of construction ,and arrangement which will become apparent' from a consideration ofl the following specification and the accom- "panying drawings, wherein Fig. 1 is a front elevation, partly in section, off'a range' showing rmy oven incorporated therein, andl Fig. 2 is a vertical sectional viewtaken on line 2 2, Fig. 1.

A range, indicated generally by numeral 10, is shown which -is adapted, in the modification illustrated, for burning gasl as a fuel. The oven, indicated generally by 1.1,

is shown as conventionally incorporated 1n the range structure, a combustion chamber 12 being positioned beneath said oven in the usual manner, and having a burner 9,I or the like therein. The combustion chamber andthe ovenfmay be provided with common outer side walls 13, which are provided with suitable heat insulating material 14, as shown in Fig. 1. rlfhe doors 15 and 16 may be of conventional type, preferably hingedat the bottom, as shown, an also provided with suitable heat insulating material 17. l

The oven bottom 18 together with the d. through lining 19 form a Hue 20 between lthe oven and the combustion chamber, as shown. Flue 20 communicates through apertures 21 *in the oven lining with the interior of the oven. Intake Hue 22 opens at its lower end to the atmosphere,l and is located at the rear of the combustion chamber and conducts air in proximity yto the back wall 12? ofthe combustion chamber to initially pre-l'ieag'l the same, a spacer sheet 12 be ing provided't'o insure that the incoming air passes close to or vin contact with the said-wall 12b. Adjacent the top of wall 12b a division sheet 23 is secured in the relation shown. This sheet', vtogether with Hue 20 and into oven 11. The Hues de-n scribed may preferably be of the same width as the combustion chamber 4'and theoven.

'The air is allowed to escape from the ovenv through vents 11b provided in the upper portion of rear wall 11 and passes through aperture 24SL of the rear flue wall 24 and intol escape Hue 27 whence it may be conducted frpm the room in the usual manner. rEhe escaping air is prevented from being drawn downwardly into Hue 26 by horizontal-partition 23a spaced from the top of sheet 23 .and extending between walls 11. and 24.

As shown in Fig. 1, the side walls 11d of oven 11 are spaced'from the outer insulated walls 13 to form Hues 28 through which the products ofl combustion from burner 9, or the like, may pass in contact with the sides vof the oven and into top Hue 29, also 'spaced Vfrom the insulated top 13a. The products of combustion pass from Hue29 through vents 29El formed in the rear Hue wall 24 and thence into escape Hue 27. It will be seen that after the air enters intake Hue 22 at the rear and base of the combustion chamber, it will be' initlally heated as it rises to contact with wall 12b of chamber 12. A still further heating of vthe air will occur as it rises upwardly Hue 25 and downwardly throug Hue 26. When the air has reached apertures 21 of the oven lining 19 it will be heatd to a relatively high temperature; 1n

fact the temperature of the air as it enters the oven will be higher generally than the temperature being maintained in the oven. The effect is thus to increase the temperature of the oven by the admission of the air, making a reduction of fuel consumption possible. I

A damper 30, shown in Fig. 2, adapted for closing pipe 31 may be provided Whereby the heat may be retained in the oven for a considerable period when desired.

It will be apparent from the above that the invention disclosed provides an oven into which the fumes and products of combustion from the source of heat can not enter or otherwise come into contact with the food y monly in use vat the present time.

It will be obvious that the modification of the invention described is Ashown more or less diagrammatically and for the purpose of illustration only, and that changes may be made therein without departing from the spirit thereof. l do not therefore wishv to be restricted to the form shown nor to the 'use of the same with the fuel mentioned, except where limited thereto by the appended claims.

What I claim is:

1. In apparatus' of the class described, an oven, a combustion chamber therebeneath, a fresh air H'ue disposed therebetween; said fresh air Hue being in communication with the atmosphere through a vertically arranged Hue adapted to carry the incoming air into contact with heated rear walls of said combustion chamber and said oven, said oven being closed against admission of air or gases from said combustion chamber.

2. In apparatus of the class described, an oven, a combustion chamber therefor, Hues for conducting the heat froml said chamber into contact with said oven on a plurality of sides thereof, said oven being closed against the admission of gases from said chamber, a Hue for conducting pre-heated air into said oven, said Hue being positioned Y between the oven and the said chamber, and

means for pre-heating the air before entering said Hue by causing the same to How through vertical Hues in contact. with heated portions of said oven and said combustion chamber.

3. The combination with an oven, of a combustion chamber therefor, and means for` ed air and products of combustion from said chamber being'conducted into direct contact with other' walls rof'said oven fory heating the same, 'but being excluded from the interior thereof.

4. In apparatus of the class described, the combination with an oven having an air' inlet, of a heating chamber beneath said oven, and means for introducing preheated fresh gair into said oven, saidvmeans comprising Hues adapted to conduct the air into contact with the vertical rear Walls of said chamber and oven and between said members to said inlet.

5. ln apparatus of the class described, the

,combination with an oven, of a heating chamber therebeneath, Hues at the sides and ltop of said oven adapted to conduct gases and products of combustion from saidv chamber into contact with the` respective walls of said oven to heat the latter, the bottom Wall of said oven having an air inlet formed in the forward portion thereof, .and Hues adapted to conduct air into contact with` the rear walls of said chamber and oven and between the latter members to vsaid inlet, whereby preheated fresh air is delivered to said oven.

6. ln apparatus of the class described i comprising an oven, a combustion chamber therebeneath, a Hue at the rear of said chamber adapted to carry fresh air upwardly and into contact with a heated wall of said chamber, additional Hues at the rear of said oven to further heat said air, and a horizontally disposed Hue adjacent the source of heat of said chamber for finally heating the air and delivering the same to said oven.

7. ln apparatus of the class described, an oven, a combustion chamber therebeneath, a fresh air Hue disposed therebetween adapted to deliver air directly into said oven, and additional Hues adapted to conduct air into contact with heated rear walls of said combustion chamber and said oven and thence into said first mentioned Hue.`

8. A range having a supporting structure, an oven and combustion chamber vcarried thereby, means for conductin air into contact with heated rear walls o said chamber and said oven to preheat` the same before delivering it to said oven, and means for conducting the products of combustion from said chamber into contact with the sides and top of said oven, said oven being closed against admission thereinto of air or products of combustion from said chamber.

In testimony whereof, I have subscribed my name.
